Originally published in 1991 and now released in paperback, Infectious Diseases of Mice and Rats is a must read for all researchers who use these lab animals. It provides practical suggestions for breeding, keeping, and identifying pathogen-free laboratory rodents. The book contains three informative sections. The first, "Principles of Rodent Disease Prevention, " summarizes methods for eliminating infectious agents. It offers information on pathogen terminology; pathogen status of rodents; and breeding, transporting, isolating, testing, and diagnosing rodents and maintaining their health status. The second section, "Individual Disease Agents and their Effects on Research, " describes the diagnosis and control of each infectious agent and the effects of the agent on research. The last section, "Diagnostic Indexes: Clinical Signs, Pathology, and Research Complications, " contains informative tables covering all the diseases listed in the volume, arranged to help in the diagnosis of infected animals. A complimentary copy of the "Companion Guide to Infectious Diseases of Mice and Rats" accompanies each copy of Infectious Diseases of Mice and Rats.
